APPLICATION

Cutting various types of wood.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

1. Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

1. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

1. Prepare a wooden workbench (Fig. 1)

Since the saw blade will extend beyond the lower surface of the lumber, place the lumber on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation.

CAUTION

To avoid possible accident, always ensure that the portion of lumber remaining after cutting is securely anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

1. Adjusting the cutting depth

As shown in Fig. 2, hold the handle with one hand while loosening the knob with the other.

The cutting depth can be adjusted by moving the base to the desired position. In such manner adjust the cutting depth and then securely retighten the knob.

1. Adjusting the riving knife

Loosen the hexagonal - head bolt used to clamp the riving knife, adjust the riving knife to the position shown in Fig. 3 and securely retighten the bolt.

1. Adjusting the angle of inclination

As shown in Fig. 4 (A), Fig. 4 (B) by loosening the knob on the incline gauge and the wing-bolt on the base, the saw blade may be inclined to a maximum angle of 45^ in relation to the base. After having completed the adjustment, reconfirm that the knob and the wing bolt are firmly tightened.

1. Adjusting the guide piece

On the circular saw, it is possible to make fine adjustment of the fixing position of the guide piece, where the saw blade and the premarked line are to be aligned.

When the saw is shipped from the factory, the linear portion of a notch on the guide piece is aligned with the central position of the saw blade. (Fig. 5 (A))

Loosen the fixed screw on the guide piece, should the fixing position be wrong, and make necessary adjustment of the position. (Fig. 5 (B))

1. Regulating the guide (Fig. 6)

The cutting position can be regulated by moving the guide to the left or right after loosening its wingbolt. The guide may be mounted on either the right or left side of the tool.

CUTTING PROCEDURES

1. Place the saw body (base) on the lumber, and align the premarked line with the saw blade by use of the front scale. When the saw blade is not inclined, the right-hand side (marked "O" on the guide piece) is the reference (Fig. 7 (A)); when the saw blade is inclined (45°), the left-hand side (marked "45" on the guide piece) is the reference (Fig. 7 (B)).

2. Ensure that the switch is turned to the ON position before the saw blade comes in contact with the lumber. The switch is turned ON when the trigger is squeezed; and OFF when the trigger is released.

3. Moving the saw straight at a constant speed will produce optimum cutting.

CAUTIONS

Before starting to saw, ensure that the saw blade has reached full speed revolution.
○Should the saw blade be stopped or made an abnormal noise during operation, turn off the switch immediately.
○Always take care in preventing the power cord from coming near the revolving saw blade.

MOUNTING AND DISMOUNTING THE SAW BLADE

CAUTION

To avoid serious accident, ensure the switch is in the OFF position, and the power source is disconnected.

1. Dismounting the saw blade

(1) Set the cutting volume at maximum, and place the Circular Saw as shown in Fig. 8.
(2) Depress the lock lever, lock the spindle, and remove the hexagonal-head bolt with the box wrench.
(3) While holding the safety cover lever to keep the safety cover fully retracted into the saw cover, remove the saw blade.

2. Mounting the Saw Blade:

(1) Thoroughly remove any sawdust which has accumulated on the spindle, bolt and washers.
(2) As shown in Fig. 9, the side of Washer (A) with a projected center the same diameter as the inner diameter of the saw blade and the concave side of Washer (B) must be fitted to the saw blade sides.
* Washer (A) is supplied for 2 types of saw blades with the hole diameters of 16 mm and 30 mm. (When buying the Circular Saw, one type of washer (A) is supplied.) In case the hole diameter of your saw blade does not correspond to that of washer (A), please contact the shop where you purchased the Circular Saw.
(3) To assure proper rotation direction of the saw blade, the arrow direction on the saw blade must coincide with the arrow direction on the saw cover.
(4) Using the fingers, tighten the hexagonal-head bolt retaining the saw blade as much as possible. Then depress the lock lever, lock the spindle, and thoroughly tighten the bolt.

CAUTION

After having attached the saw blade, reconfirm that the lock lever is firmly secured in the prescribed position.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade:

Since use of a dull saw blade will degrade efficiency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted.

2. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Inspecting the carbon brushes (Fig. 10)

The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon

brush can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the figure when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensue that they slide freely within the brush holders.

4. Replacing carbon brushes:

Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can then be easily removed.

5. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool.

Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

6. Adjusting the base and saw blade to maintain perpendicularity:

The angle between the base and the saw blade has been adjusted to 90^ , however should this perpendicularity be lost for some reason, adjust in the following manner:

(1) Turn the base face up (Fig. 11) and loosen the knob and wing-bolt (Fig. 4 (A), Fig. 4 (B)).

(2) Apply a square to the base and the saw blade and turning the slotted set screw with a slotted-head screwdriver, shift the position of the base to produce the desired right angle.
